TETRODON.] PISCES (OSSEI) GYMNODONTES. 489 



(Colour.) Of a uniform olive, sometimes yellowish, brown ; in my spe- 

 cimen, a longitudinal dark fascia extends from behind the gill-cover over 

 the first six segments of the trunk. 



As this species would seem not to be the S. Ophidion of continental 

 authors, I have restored to it the name originally given it by Willughby, 

 in consideration of its worm-like appearance. I believe it is not uncommon 

 on many parts of the coast, and is said to be called in Cornwall a Sea- 

 Adder. The ova are not carried by the male in a caudal pouch, but * in 

 hemispheric depressions on the external surface of the abdomen, anterior 

 to the vent." Obs. The S. Ophidion of Berkenhout and Turton may be 

 intended either for this species or the last.

Pennant states his having been informed that the Syngnathus Hippo- 

 campus of Linnaeus had been found on the southern snores of this king- 

 dom *. More recently, Messrs. C. and J. Paget have recorded t that it is 

 occasionally met with at Yarmouth. As, however, several species have 

 been confounded by authors under the above name, and the British one 

 has not hitherto been correctly ascertained, it is impossible to annex any 

 description. At the same time there is ground for believing that it will 

 prove to be the Hippocampus brevirostris of Cuvier.
